Diagnostic Information

This page shows the statistics for each port on the module. This information is associated with the configuration of the Service port (ETH 1) and the Device network ports (ETH 2 and ETH 3).

The frame color indicates the port activity:

green: active
gray: inactive
yellow: recoverable error detected
red: non-recoverable error detected

Statistic	Description
Frames Transmitted	Number of frames successfully transmitted.
Frames Received	Number of frames received.
Excessive Collisions	Number of excessive Ethernet collisions.
Late Collisions	Number of late Ethernet collisions.
CRC Errors	Number of detected cyclic redundancy check (CRC) errors.
Bytes Received	Number of bytes received.
Inbound Packet Errors	Number of detected inbound packet errors.
Inbound Packets Discarded	Number of inbound packets discarded.
Bytes Transmitted	Number of bytes transmitted.
Outbound Packet Errors	Number of detected outbound packet errors.
Outbound Packets Discarded	Number of outbound packets discarded.
Carrier Sense Errors	Number of detected carrier sense errors. A carrier sense error is detected when a port tries to transmit a frame, but cannot do so because no carrier is detected.
FCS Errors	Number of detected frame check sequence (FCS) errors. An FCS error is detected when a frame is corrupted during transmission as indicated by its checksum value.
Alignment Errors	The number of byte alignment errors that have been detected. A byte alignment occurs when the number of bits in a frame is not divisible by 8. An alignment error also triggers an FCS error.
Internal MAC Trans. Errors	The number of detected transmit errors that are not late collisions, excessive collisions, or CRC errors.
Internal MAC Rec. Errors	The number of detected receive errors that are not late collisions, excessive collisions, or CRC errors.
SQE Test Errors	The number of detected signal quality error (SQE) instances. Some Ethernet transceivers use an SQE heartbeat to indicate it is connected to a host interface. This detected error indicates that a transceiver has no heartbeat. Note that not all transceivers produce a heartbeat.
